OLED (Organic Light Emitting Diodes) is a flat light emitting technology, made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. OLEDs are emissive display that do not require a backlight and so are thinner and more efficient than LCD displays (which do require a white backlight).

OLED displays are not just thin and efficient - they provide the best image quality ever and they can also be made transparent, flexible, foldable and even rollable and stretchable in the future. OLEDs represent the future of display technology!
An OLED display have the following advantages over an LCD display:
As we said, OLEDs can be used to create flexible and transparent displays. This is pretty exciting as it opens up a whole world of possibilities:
Flexible OLEDs are already on the market, and it is believed that in 2018 companies will start producing foldable OLED mobile phones. The future will bring us much more exciting displays, so stay tuned
An OLED is made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted.
OLEDs aren't perfect. First of all, it costs more to produce an OLED than it does to produce an LCD - although this should hopefully change in the future, as OLEDs has a potential to be even cheaper than LCDs because of their simple design (some believe that future OLEDs will be printed using simple ink-jet processes).
OLEDs have limited lifetime (like any display, really), that was quite a problem a few years ago. But there has been constant progress, and today this is almost a non-issue. Today OLEDs last long enough to be used in mobile devices and TVs. OLEDs can also be problematic in direct sunlight because of their emissive nature. But companies are working to make it better, and newer AMOLEDs are quite good in that respect - some even consider them superior to LCDs.
